<u>Angles and Lines</u>
The figure shows two triangles WXZ and WYZ. Considering:
* Angles WXZ and WYZ are right (90°)
* Sides XW and YW are congruent (red marker on both)
* They share the side WZ.
We can conclude they are congruent. Thus, angles XZW and YZW are congruent or have the same measure:
5x + 4 = 6x
Subtracting 5x:
4 = x
Or, x =4
Thus:
We know that the angle above 10x + 54 must be 8x because of Alternate angles. And we also know that angles in a straight line add up to 180. So we can infer that 10x + 54 + 8x = 180
We can simplify that into 18x + 54 = 180
Now we take away 54 from both sides to get 18x = 126
Now divide both sides by 18 and we get
x = 7.
Now that we know that x = 7 we know that the 10x + 54 angle is equal to 124 by substituting the value of x in. We also know that 11y + 14 must equal to 124 because of vertically opposite angles. So we have 11y + 14 = 124.
Take away 14 from both sides; 11y = 110
Now divide both sides by 11 and we get
y = 10
So x = 7 and y = 10
I hope that you understood all of my steps and if this did help you a Brainliest would be very appreciated :)
Answer:
B
Step-by-step explanation:
Okay! So before we do this, first we have to understand the function. The function is,
y = ax^2 + bx + c, where a does not equal to 0.
The answer is not A, since bx is bx^2 which is incorrect.
The answer isn't C, since there isn't an ax^2 or a bc.
The answer isn't D since there a can't be 0.
The only correct answer is B, for it has all the parts.
x^2 + 2x -5.

Answer: 16
Step-by-step explanation:
72 is the record - 56 which the player has already scored = 16 points is what would be needed to tie the record
